Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electrical conductors, and particularly relates to electrical conductors that carry large-capacity, high-frequency current.
As an electrical conductor that carries high-frequency current, the effective area does not increase in proportion to the cross-sectional area due to the skin effect, so it should be used as a single piece with a large cross section or divided into multiple pieces. something is being used. However, in the former case (4), the electrical conductors of technical college trains are usually made of steel alloys or other materials with relatively low mechanical strength, so many supporting points must be shifted. , also i
The tO type has problems such as the need to deal with repulsive force caused by the current flowing in the same direction and to provide support.

The present invention has been made in view of the above-mentioned quantity W1, and its purpose is to extend a resistor part made of a material of low conductivity in parallel with high conductivity metals with lIm cornering each other. By providing a plurality of conductive parts, a large capacity current vessel can be used to conduct electricity more efficiently than a high frequency electric field cross section, thereby providing an electric conductor. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Electric conductor/Vi according to the present invention, as shown in FIG. 91 and FIG. The hole J is made up of a low conductivity resistor s3 and a plurality of energizing sl made of a metal with high conductivity and immersed in each through hole 2 of the resistor part 3.

The resistance portion aij of the electrical conductor is made of a metal or ceramic having a low conductivity with a specific electrical resistance of jμ01 or more. The metal forming the resistance part 3 is s k"
* + M 1 a O・Stainless steel is used as an alloy of these metals, such as austenitic or ferritic stainless steel, and the body is made of these metals and has a plurality of through holes in the body as described above. K to form three resistance parts having
For example, as shown in FIG. 2, a metal pipe having a circular shape and having an outer diameter gap of about α1-16 ms is connected to the cylindrical shape in a similar manner.

Note that the cross-sectional shape of the metal pipe is not limited to a circular shape, and may be a polygonal shape such as a triangular, quadrangular, or hexagonal shape.

t7t1 The metal used to form the plurality of energizing sevs of the electric conductor l should be a metal with a lower melting point and higher conductivity than the metal of the resistor part 3, such as Oll, Δg, Mul, etc. tf! :,
For example, O, alloy, Mu1 alloy, Mu1 alloy, etc. are used.

Therefore, the resistance fi5J (D area occupancy rate is 10 to 9 at the cut surface of the hazardous electrical conductor cut across the current direction of each energized W6, depending on the current carrying capacity and mechanical strength.
It is set to be 0%.

K, which manufactures an electric conductor with the above configuration in which the resistance part 3 is made of metal, first consists of a plurality of metal pipes [
The pieces are joined together so as to form a circular cross section, and the joined pieces are stored in a cylindrical container made of a plurality of gold-sided ceramics, and then placed inside each metal pipe!
! between the outermost metal pipe and the vessel or each metal pipe! 2! - into 0IIIQ high conductivity metal.

It was. K for manufacturing a resistor part J made of ceramic
First, a rod-shaped body made of ceramic is formed into a straight line with a plurality of through-holes parallel to each other in the longitudinal direction and has an l# surface shape, and the circular shape of each through-hole is A metallized layer is formed on the peripheral surface, and then each through hole is immersed in a high conductivity metal such as On.

In addition, in the above-mentioned example 7, a case was described in which the electric conductor 1 was made into a bar shape with a circular cross section and was formed in the shape of I[1I71, but the shape of the electric conductor l is limited to the shape of t. For example, Figure 8. As shown in Figures 4, 5, and 46, the shape is not limited to a linear shape, but can also be shaped like a circular cylinder, a rectangular shape, a square shape, or a plate shape. However, in the case of a book bent in this way, if the resistance m is large or small, it may be expanded into a tiM shape in advance and then formed by bending. Of course there is no O, which is 6.

Therefore, electric conductors in the shape of round rods, rectangular shapes, square shapes, etc. can be used as busbars for large-capacity current kA switchboards and other power equipment, and as coils for transformers, switchgears, etc. It can be used as a footing conductor, an electronic conductor, and various connection conductors, etc. A hollow cylindrical electric conductor is a water-cooled conductor that allows cooling water to flow through the hollow part, and is used as a conductor for high Jliil wave currents, for example. It is not acceptable to use it as a personal item. Particularly, round rod-shaped rods are suitable for transmitting operating force, such as the Loe movable rod of a vacuum breaker, and as electrical conductors that can absorb impact forces.

As described above, the present invention Fi includes a low conductivity resistance part having nine through holes spaced apart from each other in parallel, and a plurality of energizing parts made of a high conductivity metal immersed in #I in each through hole of the resistance part. Since it is an electrical conductor consisting of parts and forces, a large-capacity electrical box compared to its cross-sectional area can conduct high-frequency electricity with high efficiency, and can also increase mechanical strength, etc. Simulates the full effect of ◇
